Sunday’s meeting at Punchestown will have to pass an 8am inspection if it is to go ahead.
Cheltenham Gold Cup hero Sizing John is one of six runners set to go to post in the John Durkan Memorial Punchestown Chase, which is the feature event on a seven-race card.
However, while the track is fit for action at present, the threat of snow has forced officials into a morning inspection.
Horse Racing Ireland tweeted: “Punchestown to hold 8am track inspection due to the forecast of snow. The track is currently raceable with the ground soft to heavy.”
